I do have a couple of questions to start.

I have a hand drawn map I want to digitize using CC3. Can I scan it in and use it for tracing purposes, or I do I just need to recreate it as faithfully as possible freehand?

After I got frustrated with the tutorial, I decided to play around on my own a little just to put what I had seen so far into practice. I made a landmass bordering a sea area. I tried to run a river from inland down to the coast and link it to the coast, but when I would get to the sea area, my river would jump itself up to the top map edge every single time. What am I missing? When I did this using the tutorial maps it worked just fine, but my own map it didnt work well at all.

I dont like the width of the default river. Can I change the width it is drawn at?

Thats it for now. Thanx in advance for any assistance.
